Gate Pa and Tauranga South (they kinda border each other) are both kinda nice, but they are in an older part of town, so the houses are not yet rebuilt. Its an odd time for Gate Pa as it has become of one of the fastest appreciating areas, and it will totally see redevelopment due to the hospital. BUT many long-time locals would think twice about living there.
Having said that, the eastern side of Cameron road has some nicer houses, and is a decent neighbour hood, but the few roads immediately west of Cameron Rd (around Tauranga Girls College) are not as good.
